This customer had recently moved into a house with a Terracotta Tiled Floor in Thame, Oxfordshire and decided she did not like the colour of the floor grout and also was unable to clean off some back marks in the corners. When I went to view the property I performed a test clean on a sample area to show her that the black marks could be removed and also stripped back the tile show how much cleaner they could look. The work was agreed and I was booked to come back and completely strip the floor tile, reseal it and also change the grout colour.
Cleaning Terracotta Tile
On the first day I carefully taped up all the kitchen cupboards and skirting board to protect them from any splashes or damage. Once this was done a strong dilution of Tile Doctor Pro-Clean which is a multi-purpose cleaner and stripper was applied to the Terracotta floor tiles and left to soak into the tile for a while before being worked in with a rotary machine fitted with a black stripping pad and then a floor scrubber.
Once the whole floor had been treated in this manner the now soiled Pro-Clean solution was removed from the floor using a wet vacuum and then the floor rinsed with clean water using a spinner tool attached to the wet vacuum. The spinner tool has been a great investment for us, it applies water under pressure to the floor and at the same time removes it via an adjacent suction connection saving loads of time; it’s also a versatile tool that can also be used for Carpet Cleaning which incidentally we also do.
The Terracotta tile was now stripped of all sealer so the next step was to cleaned the black grout with Grout Clean Up which is a mild acid cleaner that can remedy a number of grout related issues, after this I rinsed the floor again with fresh water. At this point I noticed some of the grout joints had loose or missing grout so the loose grout was removed and new grout applied to the affected areas, I then had to wait overnight so the floor could dry.
Sealing Terracotta Tile
On the second day I set about sealing the floor using two coats of Tile Doctor Colour Grow which as well as protecting the floor also brings out the natural colours in the Terracotta tile. For added protection and to enhance the shine on the floor I then applied a further five coats of Tile Doctor Seal and Go, the combination of the two compatible sealers provided the effect the customer wanted. I then had to wait overnight for the sealer to dry hard.
If you recall from the start of this post, the customer also wanted to change the grout colour to a light grey so I came back for a third day to complete this. With the original grout colour being black I was concerned that the dark grout may show through the lighter grey and so I first let the customer know that it might take two coats of Grout Colourant to achieve this. However once I got started colouring the grout using an applicator I noticed that the light grey was consistently covering the black grout and therefore one coat would be sufficient.
When I had finished she was very impressed by the colour of the tile and grout and remarked on how much brighter her kitchen looked. She also asked me to come back later to do the hall floor which is a multi coloured Victorian floor.
